ROTC student Colton Haab, who shielded students from the school gunman, says CNN scripted the entire townhall event and censored him from asking the questions that he wanted to ask. CNN, the station that was caught giving giving questions to Hillary Clinton during the 2016 Presidential campaign, has denied it.
Statement from CNN: "There is absolutely no truth to this. CNN did not provide or script questions for anyone in last night's town hall, nor have we ever."
